Fig. 12 is a vertical section through the rack for holding cooking utensils and which is adapted to be placed in the insula d receptacle; Fig. 13 is a per-- s tive 0 one of the removable shelves on t e rack; Fig. 14 is a detail of one of the sides of the rack and Fig. 15 is a section upon the line Z-Z, Fig. 14. Fig. 16 is a broken detail view showing the parts emin its lower or heat-consuming.

ployed for manually opening the gas valve and automatically closing it, the valve be- 1ng shown in its open position by full lines, and 1n its closed position by broken lines.

In the drawings A indicates a suitable outer casing having an open top and formed with a door way 2 near the lower portion of one' of its sides. slide freely on the bottom 4 of the casing through the door way, its end 5 projecting below the door 6, in the door way so that it can-be used as a handle to draw the tray out or push it into the casing. This tray is adapted to carry a pro-heater B such as a gas burner having a shallow bowl 7 mounted upon a step 8 struck upwardly in the tray 3 and secured thereto by means of a screw 9. The burner cap 10 is placed on said bowl and is provided with gas openings 11 in nipples 12 projecting above the level of the surface of said cap. A strainer 13 is interposed between the cap 10 and bowl 7. At the door end of the bowl a gas needle valve 14 is secured by threading it into a wall of the bowl, said valve being controlled through the door way 2 by the handle 15. This valve is adapted to admit gas into the mixing chamber 16 which-is formedin the casingand connected with the inner chamber 17 below the perforations in the burner cap by means of the passage 18. The bowl 7,," "'called, of the preheater or burner B is formed with a wide flange 7 concentric with the burner Bexcept at its forward end where it is increased in width and extended symmetrically forward so that the whole flange when looked down upon (Fi 5) is pear-shaped in general outline. his flange receives a sealing and insulating pad 7 b of asbestos or otherequivalent material, the said pad being formed with a large circular opening forthe reception of the burner B and with a rectangular A tray'3 is adapted to opening providing for the location of 'a mixing-chamber 16 between the burner B and the needle-valve 14. When the food container C descends by gravity it is brought to a bearing upon the sealing and insulating pad 7 by means of which it is insulated and the radiation of its heat prolonged. When the food-container C fdethe lower end of the container and also the closure of the said mixing-chamber. In this passage 18 a. tube 19 is adapted to slide longitudinally to and from the inner end of the valve 14 thus regulating the proportion of air admitted with the gas into the inner chamber 1'? below th burner plate. The regulating tub-3 is ipted to he adjusted by means of a pull rod 21 positioned on the outer end of the casing and convenieutl situated so that it can be operated throw. 7 the door way.

The velve is is connected by the pipes 22 and 23 end flexible tube 24 with a source of gas supply not shown (see Fig. 5). The flexible tube 24 permits the burner being moved with the tray through the door Way for cleaning purposes thus rendering the burner portion of the appliance thoroughly sanitary and efficient and eii'ective in operation. The tray 3 is adapted to slide in a pair oi? lrniigitudinel grooves 25 in t portion of the outer casing. T he pipe is secured to the Wall of the outer casing and is provided with a main shut oil valve 26 to which the flexible tube 3% is connected. The valve stem 27 of the valve 26 carries lever arm 28 by which the valve is adapted to be closed eutl'nnaticall v in a manner to be here ineftcr described. It also carries an operat ing arm 29 to which a pull rod 30 is con nected having a. handle 31 by which the rod can be operated in and out through the ens ing to open and close the main shut off valve by hand.

The door 6 is secured to the front Wall of the outer casing along its lower edge by means of the hinge connection 32 and carries upon its inner face a mirror 33. This door is adapted to swing outwardly and. downwardly to assume an effective angle whereby the burner can be seen by an attendnnt when looking dmvnwardly upon the micro the swinging nary-cement of the door being hunted by 2 stop shoulder 34 in the term of a strip which secured to the outer face of the door. A catch 35 is provided hv which the door may no loclzed in closed lion, id (etch being adopted to 011g: over the upper edge of the door way.

The rim of the outer casing extends in wardly and is turned dovvn to form {t centrally disposed depending cylindrical wall 36 in which an insulated foodronhiner or receptacle C is adapted to slide vertically and freely. This receptacle has a double side and bottom wall, the space between the adjacent inner faces of said walls being filled with suitable poor heat conducting material 37 such as ground cork. The hottom of the receptacle is formed with a contrally disposed opening 38 fitting over the burner of the preheater B and its top is closed by a removable cover 39 having double walls spaced apart for insulating purposes.

This supportin YOl is provided with a handle and 'l'm'mell with u shoulder 63 which is adapted to catch over the edge 64 of the slotted plate 55 surrounding the opening 60 to hold the median portion of the yoke up and the insulated receptacle in superior position as illustrated ,in Fig. 4 so that a draft opening formed between the pro-heater and the inner receptacle. The operatingjever 2 on the gas valve 26 is positioned in i'he path of an arm 90 (see Fig. 8) on t v 53 u'luireby 1 permit the gas-valve to be nmnunlly opened by the rod 30 when the mo ceptacle C is in its raised or lie-u,- position, as well as provide for nut-mun Cally cutting oil the supply of gtif from the burner when the said receptacle descends into its lower or heat-conserving position, alnd whereby also the said gas 'ulvc prevented from being opened except when the receptacle C is in its raised or heatchar 'ng position. By reference to Fig it will be seen that when the re eptacle C has been lifted'into its raised position. the man ual operation of the rod 250 will muse the arm 38 to be lifted into position to be open ated upon by the arm 90 the moment the said receptacle begins to descend following the automatic disengagement of the shoulder 63 from the left hand edge the snpporting-plate 65. The slot (34 (see Fig. ll) and the free connection between the lifting allows the rod when raised or lowered to be Hii'sttl hatch ally and either extreme position of said r d in said slot is indicated by the words (*n" and Oil which are suitably inscribed upon the surface of the supporting-plate 65.

The degree of turn u; ite l l5 nnd 30 (i1uli cating minutes, starting at Zero) upon the casing A (see Fig. 2). When the crank handle 89 is in zero position and the insulated receptacle closes the rod 59 is free to be lifted and its shoulder engaged over the edge of the plates 65. The rod 59 however cannot be set in position until the crank handle 87 has been moved from Zero p0sition and set for the desired number of minutes the device is to be operated. The raising of the rod 59 lifts the insulated receptacle and permits the opening of the main control valve 26 through the operation of the pull handle 31. The turning of the crank handle 89 winds the clock work mechanism and after the clock work mecha nism operates for a pro-arranged time the stop wheel 97 revolves until the stop 85 engages the notch 86 whereupon the spring his secured under tension to the outer casing and the arm 81. lifts said arm with its stop 85 into engagement with the notch 86 thus stopping the clock work mechanism and tilting the arm 76 causing its outer end t push the rod 59 in the direction of the arrow indicated in Fig. 9 out of engagement with the edge. 04 thus releasing the insulated receptacle and causing it to close over the burner. and shut off the supply of gas.

In operation after the rack and the cook ing utensils have been placed in the insu lated receptacle the cover 39 adjusted over said receptacle with the lever arm .30 placed over the standard 51. The timer is then Set for the desired number of minutes the burner to be operated and the handle 62 raised and engaged in position over the edge 64 of the plate 65. In this position the valve 41 is opened as illustrated in Fig. 4 through the operation of the spring and lever arm 47. The door 6 is then opened and pull rod 30 drawn out opening the main control valve 26. The gas from the burner is then ignitci'l and the remainder of the operation is automatic as fully set forth in the above description. The amount of gas and air admitted to the burner may be regulated from time to time by adjusting the gas valve 1-1 and the regulating tube il by means of the handles 15 and 21 so as to produce proper cflllllillStiOIi of fuel which can be ascertained by looking down into the mirror 33 and in specting the condition of the flame.

In accordance with the patent statutes l have described the principles of operation of my invention. together with the apparatus which l now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is onl' illustrative and that the invention can be earritd out by other means and applied to uses other than those above set forth w thin th M i f rise fa' llowiu claims.

I do not hroadiy claim in this application a i'oi'al-containcr and prehe-iter one of the said parts being liilflalmiwith respect to the other, combined with spacing-mechanism the releasing function of which is controlled by automatic mechanism, and other broad features which are claimed in my copending application Serial No. "(1 1L630 filed July 2t), 1912.

The term cocking n'iran is used herein to eXpress the einlwlimrnt and mode of operation which is ery e sential to successful cooking. and which I i=t'lli,\t to be an entirely new i ea of means in this art. in other words, in the construction above described. the \alvc shutting (iii the fuel supply is manually opened. subject to a force (which is illustrated as the weightof the chamber but is not limited thereto) constantly tending to close the valve but held in abeyance by a device (which is here illustrated as the shoulder (54, but is not limited thereto) capable of being tripped or released by the timer so as to permit the cocked parts to return quickly and automaticaltv to nncocln-d position. This same mode of operation in the above described construction also controls the unsealing and selling of the cooking chamber. The suc ccssful cooking apparatus should be adapted for maintaining preheating conditions subject to a widely var ving range of time, to be determined by the cook in accordance with the article to be cooked. 'lhese variations may extend all the way from a few minutes to a very much longer time. At the expiration of this time. whatever it may be. the cooking apparatu should automati cally terminate the preheating or fire cooking conditions and convert them. without human attention. into final or tireless cooking conditions. Now the cocking means above referred to is of great importance be cause the operator may set and rock the device to a point corre pomling with any time or preheating or lire cooking that the article to be cooked demands. and Klaus place the devi e in a pi'isition to be tripped or (li 'li:ll'; "t"l automatically by the timer at the pre i time when the preheating con ditions are to be converted into final or tireless cooking conditions.

An idea of means embodied in the apparatus above described which I believe to be an entire innovation in this art is autou'iatic mechanical means for effecting without human attention the transition from cooking with fire to cooking without tire. whereby the cooking which is begun in an open oven heated by a tire. is continued and rom 'ilcted in the same oven by conserved heat. all without any attention on the part of the cook other than to set the apparatus and light the tire.

l llo 1:2 natc the pro-iod oi the c mstrnction shin-n and described, I by the means employed for lifting the foodcontainer at'the time of setting of the apparatus, this energy or force being restrained or held in aheyance during the period of fire-cooking by the cocking means and released by the automatic operating means which is adapted to be manually set for varying the period of tire-cooking occasion may demand, whereby the relation of the period of fire-cooking to the period of tireless-cooking may be pre-arranged by the operator prior to the use of the apparatus which automatically makes the transition from fire to fireless'cooking in consonance with the preparatory manual setting of the apparatus by the operator.
